Temperature-dependent sex determination in crocodilians names in Savannah

In crocodilian species—the most studied of which is the American alligator— both low and high temperatures result in females and intermediate temperatures select for males. Once the most likely map order had been derived, sex-specific map distances in centimorgans cM were estimated for each linkage group using the Kosambi [ 61 ] mapping function.

The library consisted of all vertebrate TEs identified in RepBase [ 71 ] and a set of potential TEs identified by applying RepeatScout [ 72 ] to both raw data and to the current assemblies D.

All family cohorts in this panel were selected from offspring, and family sizes ranged from 14 to 18 individuals. For the American alligator genome, we are following the Allpaths-LG recommended pipeline [ 66 ] of a combination of high coverage pairs of overlapping reads with a second, moderate coverage, longer insert mate-pair library.

Ideally, the addition of further microsatellites would be desirable due to their high levels of heterozygosity. Conservation Biology. In addition to genomic sequences and mapping information, both Sanger and transcriptome data for the crocodile and alligator are available [ 6364 ].

J Genet. At this point, little evidence supported TSD as a possible mode of sex determination. The warmth early in the season ensures female-biased broods that then have more time to grow and reach maturity and possibly reproduce before they experience their first winter, thereby increasing fitness of the individual.
